This game is a total conversion of Oblivion. Since it uses the same executable as Oblivion, you should be able to play it with the official Oblivion profile with DirectVR and everything. This is an alternate profile (for Oblivion as well).
I recommend using my gamelauncher: see
– Rename Oblivion.exe to Oblivion_N.exe
– Do not start game with Nehrim launcher
– Optimized for Cinema Modes
– FULL VR available
– Profile available at the cloud
